Previous owner of my main laptop installed the most modern intel WiFi chip, [AX200] to be precise. Unfortunately, chip does not have drivers for beloved Windows 7. Yeah intel dropped support in 2019. So, i have to downgrade wireless card. Found on eBay compatible [Dell WiFi 1820] : the last one to support Windows 7 operating system. I always loved Dell’s Precision series for super easy installation of hardware upgrades.
